This paper discusses the three outreach projects in Kent, a girls grammar school with a mixed sixth form. Due to the selective system in Kent they have around 100 potential feeder schools with their Year 7 intake of around 150 arriving from about 70 different primary schools, some of which are independent. In this article, the author describes the three outreach projects which his mathematics and computing specialist secondary school is involved. One of the main areas that has challenged and surprised them as teachers is the confidence that Year 6 have and the high levels of numeracy. It has helped them to realise that some of their KS3 students do well because they can work well with numbers, and are not necessarily picking up the new skills they are hoping to teach them. Furthermore, the author explains the impact of the outreach work in their own lessons.
